Now that the attack has slowed down, Harry was able to easily dodge it by simply moving to the side.
Boom!
After Harry dodged it, the slash continued in its path before crashing into the wall behind him with a loud bang.
Smoke gently rose up from the wall due to the force of the crash, but even though that attacked contained a large amount of mana and power, it still didn't manage to leave even a dent on the wall.
Meanwhile, Nathan's eyes widened slightly in shock, as he watched Harry easily escape his attack.
He hadn't actually meant to use such a powerful attack so early in the duel, he was simply caught up in the moment, so he instinctively used one of his more powerful attacks.
He had expected that attack to badly injure Harry, and he even felt quite remorseful after releasing the slash.
